I have also noticed the different technique = needed to set the string during fine tuning. Firm test blows usually = have no effect, I have to make more micro moves with my hammer to place = the tension properly, in the tenor and I was wondering if the material = under the felt would fail causing it to cut a channel making it contact = more of the understring felt. I like your idea of the brass half round = with thick understring felts and I'll experiment with this if time = permits.=20 I'm starting to do more with major repairs and refurbishing of original = components and I frequently check the archives of this list to see what = alternatives others have used sucessful or not. Thanks to everyone!

The Steinway tenor = understring felt develops a grip on the strings over time which becomes = the most obnoxious impediment to reliable rendering of strings during = tuning. Unless you absolutely have to remain true to S&S original = design, consider a low-friction substitute, such as brass half-round. = You can lay a strip of thick felt on either side of the brass to damp = the duplex, but the brass supports the string and allows it to move = during tuning. As seen on many fine asian pianos.
